how to add a row dynamically in .jrxml file

[NP16]

HI,

could any one give an advise of how to add a row dynamically , ie only add row if user selects Yes to a question .

at moment we are adding the rows as static text, below is the current code , so i should only add 'Question 1 user has to select Yes or no' only when user selects Yes.

thank you
